Check the quality and purity of dyes, pharmaceuticals, food products, and raw materials. Also known as spectrophotometers, these meters measure how much light is reflected by the sample at different wavelengths, so you can analyze features such as color. They work on everything from solid objects to clear coatings. Just point the light toward your sample.

Aperture sizes control the amount of light you expose your sample to. Use the 11 mm aperture to measure textured samples and average color over a larger area. The 6 mm aperture is best for general purpose measurements. The 3 mm × 1 mm aperture measures small samples.

Diffuse illumination distribution means these meters scatter light around your sample for even coverage. This gives you accurate readings on rough and uneven surfaces. The 8° illumination angle reduces light reflections when measuring glossy materials.

Color spaces give numbered color values for standard colors in different industries. These meters support standard color spaces for printing, textiles, digital displays, food and pharmaceuticals, and lighting design.

Color distance formulas measure how different two colors are from each other. ΔE76 is used for comparison in general purpose, non-critical applications. ΔECMC is often used to measure textiles, ceramics, and uneven or glossy surfaces. ΔE94 is often used to measure paints and coatings for vehicles. ΔE2000 is the most accurate and precise measurement formula. It is the standard adopted by ISO. You’ll see it used in applications where color measurements are more critical, such as laboratories or pharmaceutical manufacturing facilities.
